If it's only once in a while, you can devote a bit of manual effort. When you see the XML parsing error, you can go back, right-click on the link, and choose "Save link as". Then edit your copy of the HTML to correct the error. Open your corrected copy in your browser.

By deleting the "</table>" tag that was noted in the parsing error, I was able to view the page that you indicated.

This will break hyperlinks and is also inconvenient given that there are multiple pages on that site that are broken. Isn't there a special URL of setting to get XHTML parsed as HTML? Also, I am not actually interested in fixing the markup and want to have the flexibility of browsers being able to parse malformed HTML without complaint. Having some display errors is fine, as long as I can read the page.
